The Hydrema 922G series is a powerful line of 20 ton dump trucks designed to tackle a wide range of tasks on construction sites and in industrial environments. These machines are known for their reliability, efficiency and versatility. The 922 series includes the standard 922G model, as well as the 922HM, 920G and this narrow version; the 922G 2.55.

With advanced features and user-friendly controls, these dumpers are a reliable resource for contractors and professionals who demand reliability and efficiency on their jobsite.


The Hydrema 922G 2.55 is a compact and narrow version of the versatile 922G model. This dump truck has been designed with special attention to space constraints and easy maneuverability. With a narrower construction compared to the standard version, the vehicle width is kept below 2.55 metres (8.3 ft), making it ideal for working in confined areas and where space is limited. Despite its compact size, the 922G 2.55 retains the impressive performance and reliability that characterizes the Hydrema range.


The engine in the 922G 2.55, like the rest of the 922 G series, is a powerful Cummins B 6.7 liter 6-cylinder engine with Stage 5 emissions. It is equipped with DOC, DPF and SCR catalyst with AdBlue addition. With 24 valves and common-rail turbodiesel with intercooler and an electronically variable turbocharger, it delivers an impressive maximum power output of 231 kW (314 hp) at 2200 rpm and a maximum torque of 1288 Nm at 1500 rpm.

The transmission in the 922G 2.55 is a ZF ERGOPOWER 6 WG-210 automatic transmission with 6 forward and 3 reverse gears. It has 100% lock-up in all gears and offers both automatic and manual shifting. The dumper's maximum speeds are 31 mph forward and 19 mph reverse and it can achieve an impressive maximum tractive effort of 223 kN. This efficient engine-transmission combination gives the 922G 2.55 the power and performance needed to handle different terrains and tasks.


In the 922G 2.55 you'll find an advanced chassis that's engineered with precision and durability to ensure ultimate stability in all conditions. This articulated chassis is equipped with a pendulum rod and dual hydraulic stabilizer in the articulated joint. The chassis is made from high-strength steel to maximize strength while minimizing vehicle weight. This combination of robust construction and lightweight materials makes the 922G 2.55 a reliable and efficient work partner that can handle demanding tasks with ease. With a swing angle of +/- 12 degrees, the machine can navigate even the most challenging terrain with confidence and stability.


The axles on the 922G 2.55 combine performance and durability. The front axle features electro-hydraulic suspension and individual levelling, ensuring optimal position and stability. A heavy-duty differential lock with 75% locking action improves traction. The rear axle is a heavy-duty bogie axle with reduction gears in the hubs, a robust and maintenance-free solution with a large swing angle. This gives the machine solid reliability to tackle demanding tasks.


At the heart of the Hydrema 922G 2.55 you'll find a powerful Cummins B 6.7 liter 6-cylinder engine that meets Stage 5 standards. It is equipped with DOC, DPF and SCR catalyst with AdBlue addition, ensuring environmentally friendly operation. This 24-valve common-rail turbodiesel delivers impressive performance with electronic variable turbocharger. With a maximum power output of 231 kW/314 HP at 2200 rpm and a torque of 1288 Nm at 1500 rpm, this engine is ready to tackle the most challenging tasks with ease.
